The first few pictures were an overview of the site. Once the grid began the photos were taken in order from A5 through A1, B1 through B5, C1 through C5. The letter D grid was followed with zoomed out and general pictures because the grid was going away. The pictures then went all the way down to J without a definite order since there was no grid. Lastly, closeups were taken from J back to A of many of the objects we felt that could be important in the identification of the wreck.
Dive Plan: Air The exact amount of air in each tank will not be known until we read the gauges (1800-4500 PSI), but we will assume they are full and ready for use if their caps are on, the tank test date checks out(within 5 years) and the air tastes normal(like nothing). Each diver will be able to use two tanks for the dive. Also, we will be given a limit to how low of a PSI the tanks can be drained too. We should be out of the water at that point. Lastly, there are several options if you run out of air or there is a system malfunction in your air supply. You should always be near a prearranged buddy if you need to use their "octopus" or to buddy breathe in the event of an emergency. A last resort in the pool would be to surface by dropping your weights if you are wearing any.
What are going to be the limits in the untested new UD pool?
SInce no class has been in the new pool yet, we do not know how reflective the tiles on the bottom of the pool are and how that will affect our ability to take pictures directly into it without the flash/strobe ruining the shot.
At first, we will take photos that we feel gives a general overview of the wreck site. We will need to collaborate with the surveyors and coordinate hand signals so you can tell us what you feel would be beneficial to our team in solving the puzzle of what we believe was found. Communication underwater will be the key to successfully creating a gridded map using photos we have taken. Once we leave the water, the photos will be our only direct link to the wreck sight. In order to take a good picture, we will need to shoot up and maintain a close distance to the object. Also, a strobe light will be used to prevent the loss of color, pointed at approximatley a fourty-five degree angle to the target object. Lastly, we will need to take measurements under water because using the photos for a scaled measurement will give innacurate readings(a foot underwater may appear as much as 16" in our photos even if they are taken correctly).
